MD simulation of primary radiation damage in metals with internal structure

Abstract

A review on simulation of the primary radiation damage (PRD) and formation of radiation defects by atomic displacement cascades is conducted. Results of the simulation by the molecular dynamics method of the atomic displacement cascades and peculiarities of their interaction with the defects of the internal crystal structure (point defect, pores, dislocations, grain boundaries (GBs), and free surfaces) are given. It is shown that the defects exert a significant impact on the evolution of the atomic displacement cascades and formation of the PRD in metals.
